Aero the Acro-Bat is a Super Nintendo and Mega Drive/Genesis game created by David Siller (of Maximo: Ghosts to Glory fame), developed by the now defunct Iguana Entertainment, and published by Sunsoft on October 1993.
Inspired in part by the "mascots with attitude" trend that was common following the introduction of Sonic the Hedgehog, it featured a red bat named Aero, who works and lives in a circus. He must defend the circus from an evil ex-clown called Edgar Ektor, who used to work in the same circus and wants it shut down forever. Aero must also deal with the sidekick Zero the Kamikaze Squirrel.
The levels are played in typical 2D platforming, but in order to clear levels, the player must accomplish certain tasks so that the exit warp can be revealed. Those tasks include passing through hoops, step on platforms until they disappear, ride roller coasters, etc. There are 4 worlds with 5 levels in each one, and the levels are large, many of them containing awkwardly positioned spikes that kill instantly.
Aero the Acro-Bat 2 is a video game released by Sunsoft in April 1994. It is the sequel to Aero the Acro-Bat and dedicated to famed Brazilian racer Ayrton Senna who died in a car crash during a Grand Prix.
